If i look via time on the console on our servers NW 6.5 SP 5, i got
that output

Time zone string: "CET-1CEST"
DST status: ON
DST start: Sunday, 30 March 2008 2:00:00 CET
DST end: Sunday, 28 October 2007 3:00:00 CEST
Time synchronization is active.
Time is NOT synchronized to the network.
Friday, 28 September 2007 7:09:49 UTC
Friday, 28 September 2007 9:09:49 CEST

I wanna have only this timezone enabled on our servers
Friday, 28 September 2007 9:09:49 CEST

because if our users saveing any file it will be shown as modified with
the UTC Timezone and thats not right for our Country.

Any tipps?
